Method and apparatus for reducing redundancy in residue signel in video data compression

An apparatus for processing video data compression, comprising:

• an error signal predictor module configured to predict a reconstructed prediction residual signal (RPRS) from a reconstructed residue reference frame (RRRF);
• a subtractor module to identify an error of residue signal (EORS) by subtracting the RPRS from a prediction residue signal (PRS) of a Macro Block (MB) from a prediction signal (PS) corresponding to the MB;
• and
• an error signal selector module configured to:
• compare the PRS of a current MB and the EORS;
• and
• identify a residue signal having a least error value, wherein the error signal selector module identifies the residual signal by correlating the prediction residue signal of the current MB and a reconstructed prediction residue signal (RPRS) of a reference frame.

A method for processing video data, the method comprising:

• generating a prediction residue signal (PRS) of a macro block of video data;
• generating a reconstructed prediction residual signal (RPRS) from a reconstructed residue reference frame (RRRF);
• determining an error of residue signal (EORS) by subtracting the RPRS from the PRS;
• and
• generating an encoded bit stream for transmission based on the EORS.
